CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 422,711, dated March 4,1890. Application filed June 5, 1889. Serial No: 813,207. (No model.)

To all whom it may concern:

Be it known that I, STEPHEN Rocnns BROWN, a citizen of the United Statesof America, residing at W'ichita, in the county of Sedgwick and State ofKansas, have invented certain new and useful Improvements inCultivators, of which the following is a specification, reference beinghad therein to the accompanying drawings and the letters of referencethereon, forming a part of this specification, in which- Figure 1 is atop plan view of my invention. Fig. 2 is a side elevation of the same.Fig. 3 is a detailed perspective view of one of the pair ofshovel-beams. Fig. 4 is a side plan of the double-arched axle of thecultivator, showing the tongues in cross-section and a plan of thedraft-equalizer. Fig. 5 is a perspective view of the casting which clipsto the axle for supporting the lower draftsheaves and to which theshovel-beams are pivotally connected; and Fig. 6 is a side view of theadjustable arch which connects together the pairs of shovel-beams, and acrosssection of the beams to which it is connected.

This invention relates to certain improvements in a three-horsecultivator for cultivating corn and the like, adapted to tend two rowsat the same time by a single operation; and it consists of adouble-arched axle mounted on -a pair of traveling wheels, and providedwith a pair of tongues arranged to accommodate a horse between them andone at either side of a chain draft-equalizer operating oversheave-wheels secured to the axle by means of castings clipped to theaxle on a line parallel with the axle-spindles, and connectingequalizing-beams pivotally secured to the upper part of the arches, andof a set of four pairs of shovel-beams pivotally connected to the axle,a pair either side of either arch, each outer pair of beams beingconnected to the adjoining inner pair by an adjustable arch, and eachinside pair is provided with. a handle for guiding the shovels.

Referring to the drawings, A represents the axle, formed with thetwoarches A A.

WV WV are the traveling wheels, which are mounted on and support theaxle.

T T are a pair of tongues, one being secured on the top of each arch Anear their inner part by means of clips, as shown.

right and left position for supporting the I outer lowerdraft-equalizing sheaves S S, and are secured to the axle A, as shown,by means of clips, and are provided with rear-extending perforatedplates (Z d, to which the outer pairs of shovel-beams are connected,.and with each a forward-extending hollowed. arm e e, which supportsthat portion of the equalizing draft-chain leading from the sheaves tothe whiffletrees. c c are similar castings simi larly connected to theaxle between the arches A A and support the inner lower draftequalizingsheaves S S, and have connected thereto the inner pairs of shovel-beams,as shown.

S S are a pair of equalizing-beams, respectively pivotally secured tothe upper part of arches A A at a point about one-third way from theirouter end for the purpose of connecting and supporting the draft-chainat the arches, so as to provide free way under the arches and alsoequalize the draft on the chain; and D is the draft-chain, and isarranged connecting either end of each equal izer S thence down ateither side of each arch about the outer sheaves S S and about sheaves SS, having a whiffletree connected at each end opposite the said endsheaves and a whifiletree connected to its center opposite the centersheaves, so that draft to the said whiffietrees will be equalized byreason of being connected through the medium of said chain and theequalizers S S It will be observed by reference to the drawings that Iarrange the sheaves at an angle corresponding with the angle of thechain where it leads down from. the equalizingbeams S S and therebyrelieve the sheaves from side friction.

B B represent the outer pairs of shovelbeams, having the ordinaryshovels, and are pivotally connected with the axle adjacent the outerpart of the arches through the medium of the perforated plates (1 d ofcastings c c and the intermediate couplings Z Z, which are provided witha perforated section pivotally connected with plates cl d by means ofbolts engaging in said perforations in a vertical position, thuspermitting the said beams to move laterally on said pivots, the oppositesections of said couplings being forked and arranged to receive theforward end of said beams between the forks, and both the forks andbeams are perforated and pivotally connected by means of bolts arrangedhorizontally, thus permitting the said beam to move vertically on saidpivots.

B B represent the inner pairs of shovelbeams, also having the ordinaryshovels, and are pivotally connected with the axle adjacenttheinner'part of the arches by means of plates d d, couplings Z Z, andpivotal bolts in the same manner as the onterbeams. Each pair of innerbeams are adjustably connected near their outer part with the adjacentouter beams by means of the adjustable arches R R, which are providedwith a series of holes and secured to the desired lateral adjustment bymeans of the bolts 9 g, as shown, thus establishing twoindependently-adjustable sets of beams and shovels, each set adapted tostride arow of corn with two shovels at either side of the row, and bemanaged by the operator traveling between the rows by means of thehandles H H, which are respectively secured to the inner beams B B, asshown.

P P are hooks respectively depending from the inner rear end part of thetongues T T, and P P are upright loops respectively secured to the innershovel-beams B B, and are adapted to hold the sets of shovels off theground when the beams are raised, and they are hooked over hooks P P,which is done when transporting the machine.

For equalizing the weight of the end of the tongues T T each tongue isprovided with a separate neck-yoke V, each presenting twothirds itslength to the space between the tongues, thus equalizing the said weightbetween the three horses.

In operation the center horse will travel between the rows of corn beingcultivated, and the outer horses will travel one at either side betweenthe adjacent rows, and each draw by-means of being hitched to their respective whiffletree on the equalizing-chain D, and each draw his shareto operate the cultivator.

In some instances in cultivating, the two inner pairs of beams B B maybe connected, and thus cause all the shovels to bear a like distance onefrom the other at all times, and also, if desired, a seat may beattached to accommodate the operator.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is as follows:

1. The combination, with the double-arched axle A, having the tongues TT, arranged as described and shown, the shovel-beams B B and B B, theadjustable arches R R, connecting said beams in two separate sets, thehandles H H, respectively connecting said sets of beams, the couplings ZZ and Z Z, and castings c c and c" 0, having" the perforated platesoverreaching the axle and secured thereto and pivotally connecting saidcouplings, whereby said shovelbeams are permitted both lateral andvertical movement on the pivots of said axle-connections and theequalizing-beams and the chain draftequalizer for hauling the machine,substantially as and for the purpose set forth.

2. In combination with the axle A, the castings c c and c c, clipped tosaid axle and provided with a seat, whereby the equalizingsheaves arepivotally connected at an angle with the axle with a rear extendingperforated plate, to which the shovel-beams are pivotally connected bymeans of the intermediate couplings and bolts, as set forth,an'd withthe arms extending forward from the, sheaves for supportingthat part ofthe equalizingchain adjacent the whiiiletrees, substantially asspecified.

3. In combination with the double-arched axle A, the castings c c and cc, clipped to the axle, one either side from each arch, the sheaves S Sand S S, respectively secured to said castings at an angle with theaxle, as set forth, the equalizing-beams S S respectively secured to theupper side part of the axlearches, and the draft-chain D, arrangedconnecting said equalizing-beams and about said sheaves and connectingthe whiffletrees respectively at its center and either end; thus.forming a three-horse equalizer, for the purpose specified.

4. In the cultivator described and shown, the castings c 0, providedwith seats adapting them to be secured to the axle, with extendingperforated plates for pivotally connecting the shovel-beams, withopposite-extending hollowed arms for supporting the draft-chain, andwith upright parts adapted to support the equalizing-sheaves,substantially as set forth.
